CHIMNEY-CAP.

' SPECIFICATION forming part of Letters Patent No. 300,663, dated June17, 1884.

(No model.)

To all whont it may concern.- I

Be it known that I, DAVID C. TRESIER, a citizen of the United States,residing at Anamosa, in the county of Jones and State of Iowa, haveinvented certain new and useful Improvements in Chimney-Caps; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters or figures of reference markedthereon, which form a part of this specification.

Figure 1 of the drawings is a representation of this invention, and is aperspective view. Fig. 2 is a vertical section.

This invention has relation to chimney-caps; and it consists in theconstruction and novel arrangement of devices, as hereinafter set forth,and pointed out in the appended claim.

In the accompanying drawings, the letterA designates the base of thecap, which is made in tapering form, being reduced toward the top, asshown. A tapering neck, 13, extends upward from the base, and to theneck is joined the transverse pipe 0, which is open at each end.

D represents a band-ring adapted to pass into or over the end of thepipe 0, and to this band-ring is attached, by arms E, projectingtherefrom, an obtuse cone deflector-shield, F, the convex surface ofwhich is turned toward the end of the pipe. This shield-deflector islarger in diameter than the pipe 0, being usually double the distanceacross. Its concave 5 surface 9 is turned outward from the pipe, so thatcurrents of air striking said concave surface are made to converge tothe center thereof and recoil with whirling movements,which facilitatethe escape of the smoke from the chimney through the openings h betweenthe end of the pipe and the shield-deflector. A shield-deflector isarranged at each end of the pipe 0, and usually these deflectors aremade adjustable or capable of being moved closer to or farther from theopen end of the pipe.

In order to effect this the band-ring D is made of proper size to slidewithin or upon the end of the pipe, and the arms E, which connect thedeflector to the ring, are so shaped that they will not obstruct theadjustment.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

A chimneycap having an upwardly-reduced base, surmounted by a taperingneck carrying a transverse pipe open at each end, and connected to theends of said pipe by bandrings and arms, the obtuse cone-deflectors oflarger diameter than said pipe, having their concave surfaces turnedfrom said pipe, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID CLINTON TRESTER.
